Saber tooth cat skullCourtesy kevinzimA prehistoric stag moose antler and a saber-tooth cat skull found in a cave near Farmington may be the most significant paleontological discoveries in the Upper Midwest in years.

Chris Widga, assistant curator of geology for the Illinois State Museum in Springfield, stated that radiocarbon dating on the cat skull has shown that it is about 22,500 years old, placing the cat in Minnesota at a time when glaciers still covered parts of the Upper Midwest.
